7 Application and December 5, 1921. Serial No. 5204961 To all whom itmay concern:

' Be it known that I, SHERIDAN A. WALKER, a citizen of the UnitedStates, residing at the borough of the Bronx, city of New York,

a v5 county of the Bronx, and State of New York,

have invented a certain new and useful Improvement 1n Refri erators, ofwhich the following is a speci catlon, reference being bad to-the.accompanying drawings, which tions with reference to each other andseparating them from each other. Between said 1 'form a part of thesame.

An object of my present invention is to construct a metal refrigeratorin such man+ ner as to insure protection for the contents of thesamefrom the outside elements and have thefsame adaptable at all times iorconvenient cleaning. v 1 Another object of my invention is to make myrefrigerator in such manner as will conveniently permit of quantityproduction.

Other objects and advantages of my .in- 'vention will be readily seenfrom reading this specification, taken in connection withtheaccompanying drawings, in which Fig. 1 is a perspectiveyiew of the sidewalls, stiles and railsof my refrigerator,

together with a-similar view of the inside walls thereof Y Fig. 2 isacross section of my refrigerator looking from one end thereof;

Fig. 3 is a cross section of the same look- 80 ing from the front f F1g. 4 IS a cross section looking from the.

top of the'refrigerator; and

a ig. 5 is a detail of. construction thereof. Referring now in detail tothe drawi 's,

6 represents theouter walls of the refrigerator which are made of onepiece of metal and are provided with rounded corners 7" and offsetmarginal ends'8forming flanges. The stiles 9 are gnade of substantiallyU 'form, having's'teps 10 at their'adjacent surfaces. I" haveprovided-rails .11, 12 and 13 adapted to. connect the stiles 9to,;eachother,

the ends of these rails being mitered to correspond with the steps 10 ofthe stiles 9. At the ends (if these rails I have provided flanges 14.which form spot .weldin surfaces permitting of the electrie'weldmg ofthe rails in position between their stiles.

.also provided with rounded corners 16 and marginalflangesfl. This innerwall sec-'- tion is adapted tobe inserted'inside the outer wall section6 and the flanges 17 fit over the inner wall portions 18 of the stiles9in such manneras to make a. flush io'int Theinner walls oftherefrigerator 15 are between the stile portion 18 and the inner wall15, on the chamber sideof the said we 1 portion. The flange l7 and stileportion 1 may be welded in the positions shown.

At convenient places between the inner wall portion 15 and outer wallportion 6 I. I have provided braces 19 to which are welded the saidwallportions and which perform the double oflice of supporting the wallpor wall'portions15 and 6 is an air chamber 20, which, however, may befilled with suitable heatresisting material as for instance mineralwool. T

I'The bottom of the outer wall sectionfi is provided witha floor 21which is flanged along its marginal ends 22' so as to provide a weldingsurface to connect the same with the outer wall section and'the lowerrail 11. as shown. The upper end of the outer wall section" is providedwith a cover 23 having an ofi'set .flange24 along its marginal'edge toprovide a connecting surface'to-the outer .wall section 6. I preferablyconnect said when required, as by friction. The'uppecil' part of theinner wall section is provi with an enclosure 25 having a marginalflange 26 to provide a welding surface to connect the same to theupper'en'd of said inner wall. At the 'lower end of said inner wall Ihave provided a. closure 27 having the welding marginal flange 28adapted to con nect the same to the 'bottom ofsaid inner wall.The'closure 27 is preferably provided withrounded corners as shown. Legs29 are provided to support the refrigerator clear of the floor. "I haveprovided doors 30 and 31 which may be hinged in any convenient mam'1101' to my structure and which may be fastoned in any convenient'manner in the re ister with the steps of therails andsti-les.

l have purposely omitted to show any racks or shelving in myrefrigerator as these do not form anypart of my present invention. Racksand shelving, however, of

any desired form may be used in conjunction with: my refrigerator and itis obvious that for saidpurpose, brackets may be placed in convenient 15to support t e same.

[10 ositions on theinside walls It will be observed that both stilesused in my refrigerator are of the same design and may be rolled orstamped with the same die. The rails 11 and 13 have the same steppedarrangement as the rail 12 and may be formed by the same die as thatforming rail 12 and in the same manner When thus formed, the rail may beout along its central portion for the purpose of forming the rails 11and 13. On the rail 12 I have provided Welding flanges 33 adapting thesaid rail to have welded thereto the closure plate 34.

In order to assemble my refrigerator I prefer to -weld the stiles 9 andrails 11, 12 and 13 .into one unit. The inside wall section is thenconnected through its flanges 17 with thc lmarginal ends 18 of thestiles 9 and welded in position. The top closure 25 is then fitted intothis inner section and welded through its welding flange 26 to the saidsection, and the closure 27 is fitted onto the bottom of the said innerwall section and welded thereto through the welding flange 28 of saidclosure. The supports 19 arethen put in place where desired and theouter wall section 6 is then fitted through its welding flanges 8 ontothe outermarginal edges of the stiles 9. The flanges are so arranged toform a flushed joint on the outside of the refrigerator. The outer wall(5 may then be welded to the braces 19. The bottom closure 22 is thenput in place and welded through. its marginal flange 21 to the outerwall section and the lower rail ll of the refrigerator. The legs 29 arethen put in place and connected in any convenient manner. The cover 23may then be frictionally attached or otherwise secured to the outer wallsection 6 and the top rail 13. The doors may now be put in place in anyconvenient manner as by hinging the same outer and inner wall sections,said stiles having side plates adapted to be connected to said outer andinner wall sections and the upper rail between said stiles having anupward flange therefrom, and the top closure of the outer wall sectionbeing adaptedto 'frictionally connect with said outer wall section andsaid upper rail.

2. In a refrigerator, inner and outer wall sections, stiles, and rails,said stiles having side plates adapted tobe united to said outer andinner wall sections, spaced closures for the top and bottom of saidouter and inner wall sections respectively, the upper rail beingprovided with an upwardly disposed flange, and the top closure of theouter wall section being adapted to frictionally connect with said outerwall section and said upper rail.

In a refrigerator, inner and outer wall sections, stiles, and rails, thesaid stiles having side'plates adapted to be united to said inner andouter wall sections and form a part thereof, said inner and outer wallsections having spaced tops and bottoms, a downwardly depending flangeon the top closure of the outer wall section, the upper rail beingadapted to frictionally connect with the said top closure.

' 4. In a refrigerator, inner and outer walls in spacedrelationship toeach other, stiles and rails, said rails being connected at both ends tosaid stiles and said stiles having side plates adapted .to be united tosaid inner and outer wall sections, and form a part thereof, said innerand outer wall sections having spaced tops, a downwardly dependingflange on the top closure of the outer wall section and the upper rail,and spaced said construction being such as to maintain a specedrelationship between the inner compartment and the outer compartment of100 said refrigerator.
